Windows: eBooks are great, but many applications use proprietary formats so they're only readable in proprietary apps or on branded devices. Set them free with the Hamster Free eBook Converter.

You may remember Hamster Soft's drag and drop video converter, which we've mentioned before. Their new eBook converter is very similar: drag and drop an eBook onto the app, select the destination device or file format, and click convert. The app also supports batch file conversions from multiple formats.

Hamster Free eBook Converter allows you to convert eBook files in proprietary formats for Sony, iRiver, Amazon, Kobo, and other eBook readers into a version that can be read on any other reader, or on all of them as a simple PDF or file format they all understand.

Update: Fans of the app Calibre, a FOSS licensed eBook management application (which many of you noted in the comments that you prefer) contacted us to let us know that Hamster is using Calibre's source in its eBook Converter and restricting access to the code, which would be a violation of the GPLv3. Hamster works as advertised, but the issue is serious. For more information on this, visit Calibre's Facebook Page.
